Sophisticated and highly refined methods are available to detect trace levels of silver and its compounds in air, solid waste leachate, water (the medium of most concern for human exposure), food, and other environmental media. These methods can accurately measure background levels in environmental samples, as well as levels at which health effects occur. There are no known deficiencies in the analytical methods for determining silver in environmental media, and no additional analytical methods appear to be necessary.

Bauer and Herrmann (1997) reported the eoncentration of di- -butyl phthalate in the leachate from various fraetions of household wastes from the regions of Bayreuth and Straubling in Germany. The wastes ineluded food waste, paper for reeyeling, unusable paper, cardboard, plastic films, other plasties, textiles,... 

Variations of the AAS technique are commonly used to detect zinc levels in air, water, and soil samples, as well as in certain plant and food samples. Inductively coupled argon plasma spectroscopy (ICP) is a recommended test method for analyzing solid waste samples to measure zinc. Using either the ICP method or the AAS method, operators of hazardous waste management facilities can determine whether a given sample is hazardous, based on the level of zinc in a sample of solid waste leachate. 

In this study, anaerobic and aerobic processes using sequential two-step UASB/CSTR reactors were found to form a feasible process for treating the leachate from food solid waste. COD removal efficiencies for the first and second anaerobic, aerobic and total system processes were 79%, 42%, 89%, and 98%, respectively. The COD loading rate used ranged from 4.3 to 16kg/m3/d. 

When the mercury-containing equipment is improperly disposed of on land, the mercury will eventually leachate out from the waste equipment. Once released into the environment, mercury remains there indefinitely, contaminating the soil, sediment, and groundwater. This contamination eventually enters the food chain, exposing local populations to mercury s harmful effects.2...

Phenols and substituted phenols such as chlorinated phenols and related aromatic compounds are known to be usual components of industrial wastes. Some of the larger and more common sources of wastewater containing phenolic compounds are pulp and paper mills, petrochemical refineries, plastics and glue manufacturers, coke plants, food industries and leachate from municipal waste dumps (Rao et al. 2002). Many phenolic compounds are thought to be highly toxic and carcinogenic so they are considered to be priority pollutants. 

Land disturbance and exposure of buried geologic strata to the open environment leads to sulfide oxidation (if present) and, as a consequence, water-quality degradation of runoff. For water-quality-control purposes, sedimentation ponds required by law are used as water treatment basins. Often, the pH of such basin waters is below 6, and the concentration of heavy metals is above acceptable levels. Water treatments include neutralization and removal of heavy metals as precipitates. Similar water-quality problems arise from other industrial sources, including heavy steel industries, electronics, food processing, mineral processing, and waste-disposal leachates. This portion of the chapter deals with some of the chemical agents used for neutralization purposes and some of their limitations. 

Otto Aqua-Tech HCR [High-Capacity Reactor] A high-intensity biological treatment process for purifying effluents from food processing, certain industrial processes, and landfill leachate. The waste is circulated rapidly through a vertical loop reactor, and air is injected at the top. Invented at the Technical University of Clausthal-Zellerfeld developed and commercialized by Otto Oeko-Tech. Eleven plants had been installed in Germany and Italy by 1991.
