Opis:: The aim of the research was to evaluate the advancement of the naturalisation proces that concerned the reclaimed area of the former the sulphur mine in Jeziorko. It was assessed by analising the diversity of earthworms populations from the chosen five spots (field I, II, X, XX and XXI) differentiated in terms of time and direction of reclamation. Earthworms were obtained by the mixed method, according to Zajonc. The results were analyzed statistically. On the field II reclaimed for the longest period in forest direction, all 7 species of Lumbricidae were found, whereas on field X (shorter reclamation) – 5 of them. In the open spaces of fields I, XX and XXI, representatives of the examined group were not present. On field XX and XXI, earthworms were preserved only within individual old trees (Malus Mill., Populus L. poplar) growing in this area even before the period of land degradation by the sulphur mines. Within the crowns of these trees, poor clusters consisting of 1 or 2 species of earthworms were discovered (A. rosea and/or A. caliginosa).

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:: 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:: 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.
