ABSTRACT. Cadmium is a toxic metal often found with a strong enrichment factor in coastal sediments. The sequential extraction procedure proposed by the BCR (Community Bureau of Reference) was applied for partitioning of Cd in tropical estuary sediments. The method showed satisfactory recoveries. The repartition of Cd in different phases of sediment was controlled by the residual phase (50.32 to 67.45 %). However, the exchangeable and acid soluble fraction (F1) was in general found to be the second most abundant fraction in the surface sediments (11.14 to 15.24 %), indicating that an important portion of Cd could be remobilized, thus becoming available to aquatic biota. Cd also showed different distribution patterns in the sediment phases due to the heterogeneity of the sediments, as well as the physical and chemical conditions along with the different sources of Cd in the bays. The risk assessment code investigation showed a medium risk of Cd in the estuary.

“…Cd is toxic to a wide range of microorganism; however, the toxicity is reduced when it is incorporated in sediments, in the presence of high saline concentrations (Vasile and Vlȃdescu 2010). Chromium is carcinogenic, may cause mutations, and is a teratogen in mammals (Domingo 1994).…”

Ecological and human risk assessment of long-term produced water discharge to the ocean at the Sonda de Campeche, Gulf of México

Management of produced water (PW) is a challenge for mature fields like those of Sonda de Campeche in the southern Gulf of Mexico and for the future development of deep water fields. Past studies suggest that PW effects are local; however, the risk of widespread, long-term impact on the population and ecosystem is considered low, but not verified from the published literature. The study describes monitoring events done in years 2003 and 2013, considering physicochemical characteristics, organic and inorganic environmental measurements as well as comparing the prognostic results of an environmental and health risk assessment. The study examined ambient water samples and sediments for Al, Ba, Ni, Cd, Pb, Zn, V, Cr, Cu, Fe, and As, and also polycyclic aromatics compounds included in tissues of collected fish near the discharge area and a reference coastal site assumed to be unaffected. From a regional perspective, the ecological and human risk data suggest that the effects of the present discharge are not confined locally, but increased with time and space.

High molybdenum (Mo) and cadmium (Cd) are harmful to the body, but pulmonary toxicity induced by Mo and Cd co‐exposure is unknown. To assess the combined impacts of Mo and Cd on fibrosis through M1 polarization in the lung of ducks, 80 healthy 8‐day‐old Shaoxing ducks (Anas platyrhyncha) were randomly assigned to 4 groups and fed with containing unequal doses of Mo or/and Cd diet. Lung tissues were collected on the 16th week. Results indicated that Mo or/and Cd significantly increased their contents in the lungs, and led to trace elements disorder and histological abnormality, and oxidative stress accompanied by promoting contents of H2O2 and MDA and decreasing activities of T‐SOD, GSH‐Px, and CAT, then activated the TLR4/NF‐κB/NLRP3 pathway accompanied by upregulating Caspase‐1, ASC, IL‐18, IL‐1β, TLR4, NF‐κB, and NLRP3 expression levels, and disrupted M1/M2 balance to divert toward M1, which evoked the TGF‐β/Smad2/3‐mediated fibrosis by elevating TGF‐β1, Smad2, Smad3, COL1A1, α‐SMA, and MMP2 expression levels, and decreasing Smad7 and TIMP2 expression levels. The changes of the combined group were most obvious. To sum up, the research demonstrated that Mo or/and Cd may cause macrophages to polarize toward M1 by oxidative stress‐mediated the TLR4/NF‐κB/NLRP3 pathway, then result in fibrosis through the TGF‐β1/Smad2/3 pathway in duck lungs. Mo and Cd may worsen lung damage.
