Organic Matter Causes Chemical Pollutant Dissipation Along With Adsorption and Microbial Degradation

Views on the entry of organic pollutants into matter (OM) decaying process are divergent, and in part poorly understood. To clarify these interactions, pesticide dissipation was monitored mineral soils not adapted to contaminants for 241 days; groundwater sediment slurries pesticides 399 their sterilized counterparts with without peat (5%) or compost-peat-sand (CPS, 15%) mixture addition. The results showed that simazine, atrazine terbuthylazine (not slurries) were chemically dissipated soil, CPS-amended slurries, but soil slurries. Hexazinone best amended In contrast, dichlobenil product 2,6-dichlorobenzamide (BAM) concentrations lowest while generally poor regardless plant-derived OM, only algal agar enhanced its chemical dissipation. Based counterparts, terbutryn appeared be microbially degraded i.e., would appear utmost important, could first response natural cleansing capacity environment, during which microbial degradation evolves. Consistent compound-specific environments, long-term pentachloroaniline hexachlorobenzene mineral-rich soils, dichlorodiphenyltrichloroethane (DTT) metabolites old market gardens. OM amendments changed towards observed soil; is accelerated, slowed down stopped
