“…Surface sediments from the Malaysian coast had higher Cu, Zn, As, and Cr concentrations than those from Mong Cai, while the Pb concentration was lower (Ashraf et al, 2018). In C1 and C2 from the Mong Cai coast, Pb, Zn, As, and Cr were higher, while Cd and Cu at Mong Cai were lower (Ashraf et al, 2018).…”

The Mong Cai area, coastal sediments were collected and analyzed for grain sizes, heavy metals, total organic carbon, and isotopes (210Pb, 226Ra, δ15N, δ13C) for assessing sediment quality.Which sediments common were fine sand in surface sediment, very fine sand in core C1, very coarse silt and coarse silt in core C2. The total organic carbon was highest in C2 next to the surface and lowest in C1, with content levels of 1.81%, 0.40%, and 0.31%, respectively. δ13C and δ15N in the sediment reflected the source of the organic matter mix from the marine and terrigenous sediments. Heavy metals were lower than ISQGs, exception of As in C1 and C2 were higher, in C1 showed a decline over time, while in C2 increased between 1996 and 2019. The Mong Cai area was common by sand, accumulation of heavy metals was small, impact of heavy metal pollution on ecosystems was low.

The Mong Cai area is located on the border between Vietnam and China, with the Ka Long River forming a natural border. Coastal sediments were collected and analyzed for grain size, heavy metal content, total organic carbon, and isotopes ( 210 Pb, 226 Ra, δ 15 N, δ 13 C) to assess sediment quality.Fine sand was common in surface sediment, with abundant very ne sand in core C1; in core C2, very coarse silt and coarse silt were dominant. The sedimentation rate at C1 ranged between 0.08 and 1.62 cm/year while that at C2 ranged between 0.07 and 0.51 cm/year. The total organic carbon was highest in C2 next to the surface and lowest in C1, with content levels of 1.81%, 0.40% and 0.31%, respectively. δ 13 C in surface sediments ranged from − 27.43 to -17.02‰ and averaged − 24.13‰; δ 15 N ranged from 3.12 to 6.05‰, with an average of 4.96‰; and δ 13 C and δ 15 N in the sediment re ected the source of the organic matter mix from the marine and terrigenous sediments.The sediments' heavy metal contents were lower than ISQGs, with the exception that As in C1 and C2 was higher than the ISQG. The heavy metal distribution was highly concentrated in the Ka Long estuary with low concentration in Ha Coi Bay. The concentration in C1 showed a decline over time, while the Cu, Pb, Zn, Cr, Co, Ni, and Mn contents in C2 increased over time between 1996 and 2019. In terms of heavy metal pollution indexes, Igeo showed C1 and C2 to be unpolluted to moderately polluted with As, with Li and Pb in C2; EF was moderately enriched with As; CF was moderately contaminated (Pb, Cd, Fe, Mo, and Li) in C2 and in C1 (Cd, As, Li) and considerably contaminated (As) in C2. ER of As showed a moderate potential ecological risk in C2. CD ranged from moderate degree contamination to considerable degree contamination (C1, C2). RI had low ecological risks.

“…The beach was also reported to be polluted from intense beach activities, while the clear sea became a turbid mess of brown water 40 . Similar as Zn, Cu is vital for metabolic processes 26 but high amount of long-term exposure could lead to diarrhoea, dizziness, headache and vomiting and this is likely to happen if humans were to consume contaminated seafood harvested from polluted breeding grounds 8 .…”

“…For the past decades, numerous contamination-oriented studies had been performed with the aim to describe, evaluate as well as to estimate the heavy metals distribution and their potential anthropogenic sources, their correlation with bioavailability of metals in aquatic organisms, the consumption risks, and their ecological risks 8 . However, these continuous studies on heavy metals contamination are crucial to keep updating the level of heavy metals concentration in marine environment not just because of the economic importance of these areas but most importantly for assessing impacts it has on humans and to provide scientific references for better management of the environment as a whole 9 .…”

Vertical Distributions of Zn, Cd, Pb and Cu at Tropical Coastal Sediments: In Case of West Coast of Peninsular Malaysia

The level and pollution status of Zn, Cd, Pb, Cu in sediment cores of Bagan Pasir estuary, Sungai Buloh estuary, and the coastline of Port Dickson was assessed. Based on the vertical profiles of metals concentrations, the order of metals’ concentration in decreasing manner was Zn>Pb>Cu>Cd at Bagan Pasir and Sungai Buloh stations, while Zn>Cu>Pb>Cd at Port Dickson station. Most of the analyzed metals were below the Interim Sediment Quality Guidelines and the effect range-low (ERL) at all sampling stations. The results of geo-accumulation index, contamination factor and pollution load index classified the sediments quality as unpolluted with studied metals with the exception of the element Pb at certain depths of the sediment cores as well as historical pollution at bottom sediment at Sungai Buloh station. Therefore, metal concentrations in the sediments of these stations were not at an alarming stage, however, requires regular monitoring from the authorities to maintain sustainable management of these areas especially at Sungai Buloh due to anthropogenic activities.
