Water Quality Analysis in a Subtropical River with an Adapted Biomonitoring Working Party (BMWP) Index

Subtropical rivers in developing countries often lack adequate monitoring, which makes it difficult to comprehensively determine their water quality when faced with different anthropic impacts. There are no proper protocols in the regulations to incorporate indicators and adapt them to different bio...
