Concentrations of heavy metals (As, Cd, Pb and Hg) in water collected from seven coastal provinces between December 2012 and December 2015 were evaluated. The average total concentrations (μg/L) of As, Cd, Pb and Hg in water ranged from 2.90 to 6.38, < 0.039 to 0.322, 4.26 to 10.5 and < 0.01 to 0.118, respectively. The average concentrations (μg/L) of As, Pb and Hg in suspended particulate matters (SPM) ranged from 0.392 to 7.32, 0.365 to 18.7 and < 0.01 to 0.038, respectively, whereas Cd concentrations were not detected in most of SPM samples. There were positive linear relationships between concentrations of heavy metals in water and SPM, except for Cd. The results showed that the concentrations of metals analyzed in water remained below quality guidelines for the protection of aquatic life recommended by the international and Vietnamese organizations. However, As levels in 2/103 and 5/103 of water samples exceeded the QCVN 10:2015/BTNMT for maximum permitted level using for aquaculture and aquatic life protection (20 μg/L) and the Canadian water quality guidelines for the protection of aquatic life (12.5 μg/L), respectively.

Elongation of the sand spit in Loc An River Mouth located in the Southern Coast of Vietnam was studied using a series of satellite images to overcome the problem associated with lacking data in developing countries like Vietnam. Characteristic changes of the sand spit have been figured out based on the waterlines extracted from the re-rectified satellite images. In addition, longshore sediment transport rate (LSTR) along the up-drift sand spit was calculated based on the idea of the one-line model and this value shows good agreement with the numerical calculation performed in another study of this area.

A new endemic species, Cyrtodactylus thochuensis sp. nov. from Tho Chu Island in Kien Giang Biosphere Reserve off the southern coast of Vietnam, is differentiated from all other species of Cyrtodactylus by the following combination of characters: maximum SVL 86.3 mm (n=6); no precloacal groove; 3-5 precloacal pores arranged in an angular series; a series of enlarged femoral scales contacting a wide patch of enlarged precloacal scales; 3-6 intersuparanasals in contact with rostral; 20-26 strongly keeled, longitudinal rows of tubercles at midbody; and 30-40 transverse rows of ventral scales between the ventrolateral folds. This species most closely resembles C. condorensis Smith and C. paradoxus (Darevsky & Szczerbak).

This study was conducted to analyze the spatial distribution of heavy metals from four different coastal areas in southern Pacitan, Indonesia: Pantai Watu Karung (WK), Pantai Teleng Ria (TL), Pantai Pancer (TP) dan Pantai Soge (SG). Data collected in this study included: temperature, salinity, DO, pH, sediment, organic matter and heavy metals in the sediments (Pb, Hg and Cd). The results showed different distribution patterns of heavy metals. Heavy metal concentrations, especially Pb and Hg, were found to be higher in Pantai Soge, while the concentration of Cd was higher in Pantai Pancer. An ANOVA test showed the distributions of Pb and Cd were significantly different (p < 0.01) between sampling sites. Variability of the physicochemical parameters influenced the variabilities of heavy metal concentrations among sampling sites. Overall, heavy metal concentrations in the study areas are rather low; however, attention is still needed due to heavy activities in the coastal areas of southern Pacitan that can contribute to heavy metal pollution.
