Effect of light on the degradation of two neonicotinoids viz acetamiprid and thiacloprid in soil.

abstract：:Artisanal and small-scale gold mining (ASGM) has been performed in the southern Ecuadorian Amazon since the colonial period. However, its effects on fluvial systems have been poorly investigated. Thus, in order to calculate the normalized enrichment factors (NEF) of several heavy metals in fluvial sediments of the Zam...
