Application of water pollution detector
Background:The (nitrate) link between agriculture and water quality is nutrient abundance - I've always thought the main issue was with fertilizers. Excessive nutrient loss often leads to eutrophication of surface waters. This condition can lead to harmful algal blooms (HAB), which produce dangerous toxins and cause a drop in dissolved oxygen, killing fish in both marine and freshwater ...
