“…Mucus also plays an important role in protecting fish skin against waterborne heavy metals such as Zn. Zn was chosen because (1) it is an essential microelement (Watanabe et al 1997) present in every cell and involved in the structure or function of more than 300 enzymes and proteins (Vallee & Falchuk 1993, Cousins 1998; (2) at elevated concentrations, it becomes an important toxicant (Widianarko et al 2000(Widianarko et al , 2001; (3) it is one of the most common aquatic pollutants (Bowen et al 2006), affecting both fish (Atchison et al 1987, Bowen et al 2006) and parasites (Sures 2002, Morley et al 2003a,b, Thielen et al 2004) in many ways; and (4) the reported toxic concentrations for fish and parasites are within the same order of magnitude, whereas other heavy metals are much more toxic for the fish than for aquatic stages of parasites (Cross et al 2001, Canadian Council of Ministers of the Environment 2005, Pietrock & Goater 2005.…”

“…Finally, we hypothesized that the evidence of acclimation of the epidermal tissue observed in response to Zn alone (Gheorghiu et al 2009) would also be observed in response to the combined stresses of Zn and infection. Guppies are useful test animals in aquatic experiments because they are easy to maintain and breed under laboratory conditions and they are able to survive at very high concentrations of Zn (Widianarko et al 2000(Widianarko et al , 2001. Also, G. turnbulli burdens can be repeatedly monitored over time on individual hosts, as the parasites only live on the skin and fins.…”

“…In another study [30], there was no relationship with fish size and Pb concentrations. Widianarko et al [31] found negative relationship between Pb concentrations and size of Poecilia reticulate, whereas concentrations of Cu and Zn did not change. However, the negative relationships between heavy metal concentration fish sizes are also supported in many studies.…”

“…Hơn nữa, quá trình phát triển nhanh về kích thước cá trong điều kiện sống tốt dẫn đến hiện tượng làm loãng hàm lượng KLN trong mô thịt cá, do tốc độ tích lũy kim loại trong mô thịt không theo kịp quá trình trao đổi chất và tốc độ tăng trưởng của cá. Tương tự kết quả của Mark và cộng sự, Widianarko và cộng sự [10] nghiên cứu mối tương quan giữa hàm lượng KLN (Pb, Zn, Cu) và kích thước cá (Poecilia reticulata) cho thấy hàm lượng Pb trong cá giảm khi khối lượng cá tăng lên, trái lại hàm lượng Cu và Zn tích lũy không phụ thuộc vào khối lượng cá. Hơn nữa, kết quả chỉ ra rằng hàm lượng Cu và Zn được điều hòa và duy trì ở khoảng hàm lượng nhất định.…”
