Behaviour in soil of polyethylene film and polyethylene film with starch additive

, : Behaviour in soil of polyethylene film and polyethylene film with starch additive. Water, Air, and Soil Pollution 88(1/2): 109-117

Films designated biodegradable were investigated and their actual capacity to biodegrade on burial in soil was assessed. The films tested were polyethylene and polyethylene with starch based additives and fatty acids to promote biodegradation. The samples were subjected to the action of microorganisms in soil in two ways: under strictly controlled laboratory conditions, and exposed to normal atmospheric conditions.

Forests act as efficient filters for many airborne semivolatile organic compounds (SOCs). However, most simulations of an organic chemical's long-range transport in the atmosphere do not account for this filter effect. In this study, forests...
