Assessment of agrochemical residues in wastewater from selected horticultural farms in Arusha, Tanzania

Abstract

The use of agrochemicals results to increased crop productivity and consequently offers farmers major economic returns. However, the use of agrochemicals and the adjacency of horticultural farms to streams and rivers have the potential to contribute to water pollution if control measures are not effective. The continued agrochemical use may lead to contamination of adjacent water resources which may, in the long run, cause adverse health effects to the downstream water users.
