Opis:
Pesticides are at risk due to their toxic properties in humans as well as impact on the environment and ecosystems. Indonesia has 1,336 formulations and 402 pesticide ingredients registered to control pests in various commodity fields. The negative effects of synthetic chemical pesticides are resistance, resurgence, second pest blasting, and environmental degradation. Pesticide residues on the soil and agricultural products can cause bioaccumulation and biomagnification processes. The biomagnification process can cause exposure to pesticides that enter the human body to a greater degree than the residues found in the environment. Therefore, it is necessary to research the life cycle analysis of exposure and pesticide residues in agricultural environments. This study is an observational study with a cross-sectional design. The sample in this study was 120 respondents. This research was conducted in the Wanasari subdistrict, Brebes regency. Wanasari subdistrict is the largest shallot-producing centre in Brebes regency (26%). The shallot harvest area in Wanasari district is 6,598 ha. The life cycle analysis (LCA) results of shallot farming include five stages: soil maturation, planting seedlings, fertilizing, applying pesticides, and harvesting. The emissions in shallot farming activities come from diesel fuel, pesticides, and NPK fertilizers. Chlorpyrifos pesticide residues were found with an average level of 0.6451 ppm in 9 villages in Wanasari district.

Opis:
Among nutrients and pesticides, agricultural draining ditches also transport pollutants discharged with untreated wastewater from the municipalities adjoining the ditch. When the ditch water is used for irrigation and aquaculture, risks for the environment and food production are suggested. For the conducted field study, a shrimp farm in Sinaloa (Mexico) was used to trace organic pollutants (pesticides and pharmaceutical residues) on their way from an agricultural draining ditch to a shrimp farm fed partially by the drain water. The concentrations of pollutants in the drain water ranged from 10 ng L-1 to 453 ng L-1. The pond water of the shrimp farm contained concentrations between <10 ng L-1 and 177 ng L-1. The shrimps were contaminated by pollutants at concentrations between 40 μg kg-1 d.w. (dry weight) to 3.3 mg kg-1 d.w. (fungicide Metalaxyl). Health risks for the cultivated shrimps cannot be excluded because some pesticides are known for their toxic effects to crustaceans. The concentrations of selected antibiotics in the shrimps were low and comparable with those found in the shrimps declared as seawater shrimps from a German supermarket. The incorporation of the antibiotics was probably caused by contact to the wastewater in the shrimp ponds and/or by contaminated shrimp feed. Additionally to the anthropogenic chemicals, coliforms were determined in the water (total coliforms: 30-50 CFU 100 mL-1; fecal coliforms: 0-20 CFU 100 mL-1). These values agree with the Mexican Norm NOM-242-SSA1-2009 representing a microbiological quality of water adequate for aquaculture. The number of coliforms measured in shrimp was higher than in pond water, suggesting bioaccumulation and a potential health risk for consumers.

Opis:
A wide range of soilless cultivation techniques have been developed and introduced for intensive cropping systems and for boosting the crop yield of many vegetables, mainly in greenhouses. Adoption of some local natural by-products to be utilized as a substrate growing medium to overcome soil-related problems appeared to be a promising project. Therefore, greenhouse experiments were conducted at the Baloza Experimental Station of the Desert Research Center (DRC), North Sinai Governorate, Egypt, during the two consecutive winter growing seasons of 2016–2017 and 2017–2018. These experiments aimed to investigate the effects of seven growing substrate culture treatments of separated or mixed sand obtained from sand dunes and date palm tree residues (Karenna) on plant vegetative growth, flowering, fruit yield and quality traits, and fruit nutritional values of cucumber plants (Cucumis sativus L.) Filial-1 hybrid 1101. Crop evapotranspiration reference (ETc) and water use efficiency (WUE), as well as treatment feasibility, were also studied. The experiment was set up in a complete randomized block design with three replicates. The obtained results strongly indicated that growing substrate media containing 25% sand (S) from sand dunes mixed with 75% grinded Karenna (Kg) of date palm (1 S + 3 Kg) significantly recorded the superiority of all studied characters of plant vegetative growth, number of flowers, fruit set, yield and its components, as well as fruit N, P and K contents, compared with other growing substrate medium treatments. On the contrary, the worst values of all studied parameters were achieved when sand was used alone (100% S) as a growing media. Furthermore, the highest water use efficiency and net income values were also attained by the 1 S + 3 Kg media treatment relative to the other growing substrate medium treatments.

Opis:
Based on the global goals for cleaner production and sustainable development, the pyrolysis behavior of cephalosporin residues was studied by TG-MS method. The influence of full temperature window on the safe disposal of residues was analyzed based on the “3-2-2” and “1+1” of thermal analysis kinetics, and the gas by-products of thermal degradation were monitored. Results showed that the pyrolysis of distillation residues were divided into low and high-temperature zones, including six stages. Maximum error rate (8.55%) by multiple scan rate was presented based on “3-2-2” pattern and maximum total fluctuation (33.7) by single scan rate was presented based on “1+1” pattern, which implied that the comprehensive multi-level comparison method was very reliable. The E value “E” of six stages showed an increasing trend ranging 166.8 to 872.8 kJ/mol. LgA(mean) was 27.28. Most mechanism function of stage 1, 2 were Z-L-T equation (3D), stage 3, 4, 6 were Avrami-Erofeev equation (AE3, AE4, AE2/3) and stage 5 was Reaction Order (O2). In addition, various small molecular micromolecule substances were detected such as C2H4O, C2H6, NH3, CH4, CO2 under full temperature windows and a possible pyrolysis path of residues was provided.

Opis:
Apple processing generates a huge amount of bio-waste in the form of pomace, which instead of being managed, contribute to environmental pollution. Apple pomace is formed mainly at the stage of apple processing and food production. It is valuable material that can be reused in a agriculture industry according to the circular economy concept. Unprocessed or slightly processed fruit residues can be converted into animal feed or be used as biofertilizers. Apple pomace contains valuable substances and compounds that can be successfully used in food, cosmetic and pharmaceutical products. Another form of using apple pomace is the extraction of biofuels. According to the idea of sustainable development rational management of bio-waste benefits economically, reduces environmental pollution and contributes to the reduction of greenhouse gas emissions.
Przetwórstwo jabłek generuje ogromną ilość bioodpadów w postaci wytłoków, które zamiast być zagospodarowane, przyczyniają się do zanieczyszczenia środowiska. Wytłoki jabłkowe powstają głównie na etapie przetwarzania jabłek i produkcji żywności. Jest to cenny materiał, który może być ponownie wykorzystany w przemyśle rolniczym zgodnie z koncepcją gospodarki o obiegu zamkniętym. Nieprzetworzone lub lekko przetworzone pozostałości owoców mogą być przekształcane w paszę dla zwierząt lub stosowane jako bionawozy. Wytłoki jabłkowe zawierają cenne substancje i związki, które z powodzeniem mogą być stosowane w produktach spożywczych, kosmetycznych i farmaceutycznych. Inną formą wykorzystania wytłoków jabłkowych jest produkcja biopaliw. Zgodnie z ideą zrównoważonego rozwoju, racjonalne gospodarowanie bioodpadami przynosi korzyści ekonomiczne, zmniejsza zanieczyszczenie środowiska i przyczynia się do redukcji emisji gazów cieplarnianych.

Opis:
The biodiversity of aqueous environments has been affected due to the disposal of wastewater highly contaminated with heavy metal ions, causing much damage to ecosystems. These pollutants are very toxic and bioaccumulate in living organisms. This work attempts to evaluate the adsorption of nickel ad cadmium ions using three biomasses from agricultural residues (corn cob – CC, orange peel – OP, and oil palm bagasse – PB) modified with alumina nanoparticles. The biomasses were characterized via compositional analysis and a point of zero charges to quantify the presence of lignin, cellulose, hemicellulose, and the feasible pH, taking advantage of the biomass charge. After modification with Al2O3 nanoparticles. The resulting adsorbents were characterized via FT-IR analysis to identify the functional groups that most contributed to the adsorption performance. Furthermore, the influence of Al2O3 nanoparticles was analysed on the adsorption capacities of the evaluated biomasses using batch systems at a temperature of 25°C and pH 6. All biomasses displayed a high content of cellulose, estimating a weight percentage of about 19.9%, 14.3%, and 13.1% for PB, OP, and CC samples, respectively. The FT-IR spectrum confirmed hydroxyl and carboxyl functional groups, which contribute to enhancing the adsorption capacities of the modified biomasses. Functional adsorption capacity was observed for all biomasses after modification with Al2O3 nanoparticles, achieving at pH 6.0 a cadmium removal from 92% (CC-Al2O3 and PB-Al2O3) up to 95.8±0.3% (OP-Al2O3). In nickel ions, it was estimated a broader adsorption capacity at pH 6.0 of about 86±0.4% after using the CC-Al2O3 sample, 88±0.1% for the PB-Al2O3 adsorbent, and 98±0.2% for the OP-Al2O3 sample, confirming the suitability of these Al2O3-modified biomasses for the removal of heavy metal ions.

Opis:
Tillage and plant residues influence soil attributes and, consequently, soil quality. Therefore, suitable management and maintaining the stability of soil structure is important. This study was performed to evaluate the effects of tillage systems on soil quality during a 4-year crop rotation (wheat, canola, wheat and tomato) at the Agricultural Research Center of Khorasan Razavi province (Iran) from 2011 to 2015. The study was conducted as a randomized complete block design in a factorial arrangement with 3 replications. For this purpose, conventional tillage (CT), minimum tillage (MT) and no-tillage (NT) systems together with three rates of plant residues (0, 1,500, and 3,000 kg ha-1) were applied annually after harvesting. Soil quality was determined by using the integrated quality index (IQI) and Nemoro quality index (NQI) based on total data set (TDS) and minimum data set (MDS). In total, 23 physical, chemical, and biological soil characteristics were considered as TDS and 7 out of these were selected as MDS for use in the principal component analysis (PCA). Soil quality in different tillage treatments was determined and the most appropriate indices and effective characteristics for soil quality assessment were selected. Correlation coefficients between IQITDS and IQIMDS (r = 0.69) and between NQITDS and NQIMDS (r = 0.76) showed that NQI was a better indicator for assessing soil quality. The NQITDS provided a more accurate and comprehensive assessment of soil quality. However, using MDS reduced the cost and time with proper precision. Soil quality in MT and NT treatments was more desirable than the CT system, and the addition of plant residues improved the soil quality. According to the results of NQITDS, IQITDS, and IQIMDS, soil quality in the NT system with 3,000 kg ha-1 of plant residues and the MT system with 1,500 and 3,000 kg ha-1 of plant residues were more favorable than other soil tillage treatments. Soil characteristics that decreased soil quality in the conventional tillage were soil structure, macro and micronutrients, while in conservation tillage it was micronutrients, especially Zn.

Opis:
Salinization and sodification of agricultural lands in arid and semi-arid regions of the world are two limiting factors in the crop production. This study was conducted to evalu- ate the effect of readily available agricultural residues on changing some chemical properties of saline-sodic soils. Wheat, potato, sunflower, and canola residues were separately added into three saline-sodic soils at a rate of 2% by weight and thoroughly mixed with soils. Control and treat- ed soils were incubated for 168 days at a constant moisture and temperature. The pH, electrical conductivity (EC), soluble cations, available nitrate (NO 3 -) and phosphorous (P), cation exchange capacity (CEC), and exchangeable sodium percentage (ESP) were measured during the incuba- tion. The EC increased in the response to the incorporation of plant residues, whereas the pH was reduced. The application of organic components in soils increased CEC and decreased ESP. The results showed that the maximum reduction in ESP was observed in the potato treatment because of the highest Ca2+ concentration. The average reduction in ESP of treated soil samples at the end of incubation followed this order: 16.1% (potato residue-treated soil) >12.7% (canola residue-treated soil) >11.1% (wheat residue-treated soil) >9.6% (sunflower residue-treated soil). The potato residue was the most effective amendment in changing the chemical properties of saline-sodic soils in comparison with other organic residues. The results indicated that the appli- cation of organic residues had a positive impact on reducing the soil sodicity and improving the soil fertility depending on their chemical composition.

Opis:
The results of the research on energy usage of the fatty acids distillation residue are presented. Distillation residue constitutes a material of biogenic origin, which is created only as a result of physical processing of animal fats without using additional chemicals. This material exhibits similar physicochemical properties as the heavy heating oil and may be its substitute. Industrial comparative tests of combusting of distillation residue and also of the heavy heating oil in an oil boiler were conducted. The research was conducted at the rated and minimum capacities of the boiler. It has been stated that combusting of the distillation residue of the fatty acids in a tested oil boiler does not bring about any technological difficulties. No threat of the elevated emission of pollutants into the atmosphere was exhibited. Installation of the boiler fulfill all emission standards required for combustion of the liquid fuels. Combustion of fatty acids distillation residue contributes to the reduction of the previous emission of pollutants from burning of the heavy fuel oil, significantly in scope of SO2.

Opis:
The work carried out in this article concerns on the implementation off a diagnostic procedure for hybrid dynamic systems (HDS) whose objective is to guarantee the proper functioning of industrial installations. In this context, the main contributions of this work are summarized into three parts: The first part is oriented to the modeling approach dedicated to HDS. The aim is to find an adequate model combining both aspects (continuous and discrete dynamics). The use of Neuro-fuzzy networks makes it possible to build a model of the system and to follow all the modes without it being necessary to identify or discern them. The second part concerns the synthesis of a fault diagnostic technique based on a fuzzy inference system. A Neuro-Fuzzy network based is used for residual generation, while for the residual evaluation, a fuzzy reasoning model is used which can mainly introduce heuristic information into the analysis scheme and takes the appropriate decision regarding the actual behaviour of the process. The proposed approach is successfully applied to monitoring faults of a non-linear three-tank system and the results confirm the effectiveness of this approach.

Opis:
Wykorzystywane w produkcji środki ochrony roślin mogą gromadzić się w żywności. Stosowanie ich wiąże się więc z ryzykiem, zarówno środowiskowym, jak i zdrowotnym. Pomimo odpowiednich uregulowań prawnych w tej dziedzinie, wciąż pojawiają się produkty z pozostałościami tych środków i innych pestycydów przekraczające dopuszczalne stężenia. Ze środkami ochrony roślin wiążą się również inne zagrożenia, jak np. stosowanie ich niezgodnie z przeznaczeniem, rosnąca sprzedaż preparatów fałszywych czy lekceważenie zasad BHP przez rolników. Mając te kwestie na uwadze, NIK przeprowadziła ogólnopolską kontrolę dotyczącą działań inspekcji sprawujących nadzór nad wprowadzaniem do obrotu i stosowaniem środków ochrony roślin przez producentów płodów rolnych oraz nad bezpieczeństwem żywności pochodzenia roślinnego. Sprawdzono także efektywność współpracy pomiędzy inspekcjami.
Crop protection chemicals used in agriculture may remain in food. Therefore, their use creates both an environmental and health risk. Despite appropriate legal regulations in the area, some food products contain remnants of such chemicals, or other pesticides, that exceed permitted levels. There are other risks related to using crop protection chemicals, too, such as misuse, growing sales of false chemicals, or negligence of health and safety rules by farmers. NIK carried out an audit, covering the whole country, on the activities of inspectorates that supervised marketing and use of crop protection chemicals by producers, and inspectorates responsible for food safety. The audit evaluated whether the safety system in the area is appropriate and effective.

Opis:
This research was conducted to evaluate the effects of biochar and barley residues on some physicochemical properties of silty loam soil and water erosion using water erosion sim- ulator. Biochar was produced from pistachio shells under slow pyrolysis at 500°C under anaer- obic condition. Biochar and barley residues were mixed to soils at three rates of 0, 0.5 and 1% (by weight), and 6.5 kg of soil was filled in trays with length, wide and height of 35 × 20 × 10 cm, respectively. The experiments were performed in 3 repetitions for 4 months as a completely randomized design. The results showed that application of 1% of biochar significantly increased P (phosphorus), K (potassium) and OC (organic carbon) of the soil in comparison with control. Also, application at both levels (0.5 and 1%) of barley residues significantly increased P, K, TN (total nitrogen), and OC. Application of biochar and barley residues significantly increased the mean weight diameter of aggregates, plant available water content, and saturated moisture content and significantly decreased water dispersible clay (p < 0.05). Consequently, the amount of water erosion decreased at the rainfall intensity of 60 mm·h-1 during 20 minutes. Generally, the effect of barley residues to improve soil properties was higher than the biochar.

The results showed that application of 1% of biochar significantly increased P (phosphorus), K (potassium) and OC (organic carbon) of the soil in comparison with control. Also, application at both levels (0.5 and 1%) of barley residues significantly increased P, K, TN (total nitrogen), and OC. Application of biochar and barley residues significantly increased the mean weight diameter of aggregates, plant available water content, and saturated moisture content and significantly decreased water dispersible clay (p < 0.05). Consequently, the amount of water erosion decreased at the rainfall intensity of 60 mm·h-1 during 20 minutes. Generally, the effect of barley residues to improve soil properties was higher than the biochar.

Opis:
The aim of the study was to determine the effect of different management treatments of Norway spruce post−harvest logging residues on soil properties. The study compared the impact of residues chipping and arrangement into the stacks. The investigation was carried out in the Nowy Targ Forest District (southern Poland). 15 research plots were selected for the analysis (5 plots with wood chips, 5 with stacks and 5 control ones). In May 2018, on each research plot soil samples for laboratory analysis were collected from the surface horizon (0−10 cm depth). Basic properties (pH, carbon and nitrogen content, base cations content) and enzyme activity (dehydrogenase, urease and−glucosidase) were determined. The obtained results confirm the influence of post−harvest logging residues management on soil properties. The significant differences in soil carbon content between soils of different plots variants were noted. Soils of research plots with wood chips and stacks were characterized by higher content of carbon compared to the control research plots. At the same time soils with post−harvest logging residues had a higher biochemical activity expressed by enzymatic activity. The nutrients released from decaying post−harvest logging residues stimulated the microbiological activity of the soils.
