“…In fish, lead can be absorbed from water, food, or sediment, but regardless of the route of entry into the body shows a high tendency to bioaccumulation in various fish tissues (including gills, liver, skin, and muscles), depending on environmental factors, species-specific features, concentration, and time of exposure [8,19,20]. From literature, it is known that in fish, embryos and larvae are the most sensitive life stages, and they can therefore serve as an early indicator of pollution even at low levels of exposure, which also applies to Pb and other heavy metals [21][22][23]. Nevertheless, Pb-induced alterations during development are largely overlooked, and most of the available studies have been conducted on adults.…”
