In response to the chronic overuse and misuse of pesticides in agriculture, governments in Southeast Asia have sought to improve food safety by introducing public standards of good agricultural practices (GAP). Using quantitative farm-level data from an intensive horticultural production system...

В условиях непредсказуемости социо-эколого-экономических последствий функционирования промышленных предприятий, возрастает необходимость оценки развития...

Biochar has altered plant yields and soil nutrient availability in tropical soils, but less research exists involving biochar additions to temperate cropping systems. Of the existing research, results vary based on soil texture, crop grown, and biochar properties. The objective of this study was...

The present study documents the Hg content in 45 urban topsoil samples from the highly urbanized city of Athens, Greece. The Hg concentrations were quantified by applying <i>aqua regia</i> digestion on the <100 μm soil fraction followed by inductively coupled plasma-mass spectrometry (ICP-MS) with a detection limit of 5 μg·kg⁻¹. The median concentration of Hg in Athens soil is 96 μg·kg⁻¹; ten out of 45 soil samples...</100>

We examine several determinants of farmland values in the Campine region (Belgium) using data on individual sales transactions. Since the study area is well known to have a legacy of heavy-metal pollution of land, one of the focal points is the implicit price of cadmium (Cd) pollution. We use a...

A Károly Róbert Főiskolán 1994 őszén beállított nehézfémterhelési tartamkísérlet (Al, As, Cd, Cr, Cu, Hg, Pb, Zn) hetedik évében őszi árpát (Hordeum vulgare L.), tizenharmadik évében lucernát (Medicago sativa L.) termesztettünk. A talaj és a növények arzéntartalmának...

USA is inflicting severe damage upon both the environment and its inhabitants. In 1979, the EPA estimated that in the USA there were as many as 51,000 sites containing potentially hazardous waste. The number of sites with 'significant problems' was anywhere. The EPA noted, "Industry has shown a...

Earthworms are being used to manage most organic wastes; treat wastewater; clean-up chemically contaminated soils; improve soil fertility and produce food crops. Their use in production of life-saving medicines and raw materials for industries are some new discoveries. We have successfully...
