“…Ikan bandeng budidaya juga umumnya mempunyai jumlah lemak tinggi, dan menurut Gupta dan Singh (2011), Guzman-Garcia et al (2009) dan Torres et al (2012) tubuh yang kaya akan lipid memiliki afinitas tinggi terhadap logam berat, sehingga ikan bandeng berpotensi mengakumulasi logam berat lebih tinggi, sehingga ikan terkontaminasi Cd dan Pb akan membahayakan manusia yang mengkonsumsinya (Authman et al, 2015, Riani et al, 2014dan Riani et al, 2015. Hal ini Cd dapat berpotensi untuk mengakibatkan terjadinya itai-itai disease dan Pb berpotensi mengakibatkan plumbism.…”

Seribu Islands located in the north of Jakarta Bay; it is potentially polluted by heavy metal such as Cd and Pb. The aims of this study is to prove contamination presumption, by analyzing and determine correlation Cd and Pb concentration in the sediment, in the water and on milkfish Chanos chanos cultured in this area. On this study, we collected water quality data (pH, temperature, dissolve oxygen and salinity) and heavy metals contamination (Cd and Pb) in the sediment, in the water and on milkfish. We compare collected data with quality standar and correlate heavy metal concentration between in the water and in the sediment; in the water and on milkfish organ; and, in the sediment and on milkfish organ. In general, water quality is sufficient enough to support the life of farmed milkfish. Cd and Pb contamination level in the water lied below the quality standard of Ministry of Environment decree No. 51/2004 in the last April and July. However, the contamination exceeds the standard in the last October. The contamination in sediment lied below RNO (1981), EPA (1999) and IACD/CEDA (1997). Gills, viscera and the meat of the milkfish are contaminated with Cd and Pb, yet, still lied below the quality standard of Ministry of Environment Decree No. 51/2004. The results showed that farmed milkfish in Thousand Islands are safe to eat. We also found that the correlation of Cd and Pb contamination between water and sediment is positive. The correlation of Cd is much higher than Pb. The correlation of Cd between water and viscera as well as between sediment and viscera are the most closely related than any other organ.

“…However, pristine mangroves also exist and are represented by protected areas (Cetesb, 2001(Cetesb, , 2007. It is, therefore, a contrasting scenario that has been mentioned and studied by several authors (Silva et al, 2002;Abessa and Ambrozevicius, 2008;Cordeiro and Costa, 2010;Martins et al, 2011;Pereira et al, 2011;Torres et al, 2012;Pinheiro et al, , 2012Pinheiro et al, , 2013.…”

Ecotoxicology and Environmental Safety

There is a global lack of knowledge on tropical ecotoxicology, particularly in terms of mangrove areas. These areas often serve as nurseries or homes for several animal species, including Ucides cordatus (the uçá crab). This species is widely distributed, is part of the diet of human coastal communities, and is considered to be a sentinel species due to its sensitivity to toxic xenobiotics in natural environments. Sublethal damages to benthic populations reveal pre-pathological conditions, but discussions of the implications are scarce in the literature. In Brazil, the state of São Paulo offers an interesting scenario for ecotoxicology and population studies: it is easy to distinguish between mangroves that are well preserved and those which are significantly impacted by human activity. The objectives of this study were to provide the normal baseline values for the frequency of Micronucleated cells (MN‰) and for neutral red retention time (NRRT) in U. cordatus at pristine locations, as well to indicate the conservation status of different mangrove areas using a multi-level biological response approach in which these biomarkers and population indicators (condition factor and crab density) are applied in relation to environmental quality indicators (determined via information in the literature and solid waste volume). A mangrove area with no effects of impact (areas of reference or pristine areas) presented a mean value of MN‰<3 and NRRT>120min, values which were assumed as baseline values representing genetic and physiological normality. A significant correlation was found between NRRT and MN, with both showing similar and effective results for distinguishing between different mangrove areas according to conservation status. Furthermore, crab density was lower in more impacted mangrove areas, a finding which also reflects the effects of sublethal damage; this finding was not determined by condition factor measurements. Multi-level biological responses were able to reflect the conservation status of the mangrove areas studied using information on guideline values of MN‰, NRRT, and density of the uçá crab in order to categorize three levels of human impacts in mangrove areas: PNI (probable null impact); PLI (probable low impact); and PHI (probable high impact). Results confirm the success of U. cordatus species' multi-level biological responses in diagnosing threats to mangrove areas. Therefore, this species represents an effective tool in studies on mangrove conservation statuses in the Western Atlantic.
