Which process compromises osmoregulation in freshwater fish when exposed to pollutants damaging gill chloride cells?

💡 Explanation

When chloride cells are damaged, active transport of ions is impaired because these cells facilitate ion uptake, vital for osmoregulation in freshwater fish, to counteract ion loss to the hypotonic environment. Therefore impaired ion uptake results as opposed to increased excretion, altered water influx or urea buildup which would not address ion balance.
