Soil and Groundwater Contamination by Hazardous Substances in Japan.

Hazardous Substances and Activities

Assessing soil and groundwater contamination from biofuel spills.

Future modifications of fuels should include evaluation of the proposed constituents for their potential to damage environmental resources such as the subsurface environment. Batch and column experiments were designed to simulate biofuel spills in the subsurface environment and to evaluate the sorption and desorption behavior of target fuel constituents (i.e., monoaromatic and polyaromatic hydr...

Groundwater Contamination

INTRODUCTION In the southern United States, chemicals are an integral part of the management of bare-root nurseries. The rationale for using chemicals is based on economics as they can reduce hand labor, improve the use of valuable seed, and increase seedling performance. The cost of all chemicals associated with loblolly pine seedling production averages less than 0.2 cent per seedling. The co...

The BG measurement system for hazardous substances (BGMG) and the exposure database of hazardous substances (MEGA).

German employers' liability insurance associations or Berufsgenossenschaften (BGs)--institutions for statutory accident insurance--maintain a measurement system for hazardous substances, the so-called BGMG. The aim of the BGMG is to determine and document valid results of measurements of exposure primarily for prevention purposes. The data are collected systematically, in parallel to the sampli...

Advisory Committee on Hazardous Substances

I. Review information and studies on the environmental exposure and effects of nanoparticulate silver; II. Comment on known or predicted environmental exposure levels and whether these present a human health or environmental risk; III. Comment on the nature of appropriate measures to minimise risks, if these are felt to be necessary at this point in time; IV. Consider what action should be take...
