It may be more effective to manage pollution in waterways if we can better understand the connection between heavy metals in sediments and their accumulation in green mussels. In this study, lead levels in green mussels (<em>Perna viridis</em>) were above the permissible maximum level (WHO, Malaysia Food Regulation, and the FAO). Moreover, zinc levels exceeded the FAO's maximum recommended range. The fractionate of heavy metals in surface sediment from the eastern part of the Johore Straits was investigated using the sequential extraction techniques (SET) method. In the majority of sampling stations, copper's chemical speciation followed the following order: residual > oxidisable-organic > exchangeable > acid reducible, while zinc's and lead's chemical speciation followed the following pattern: residual > oxidisable-organic > acid reducible > exchangeable. The results of Pearson's correlation studies demonstrated a substantial association between Zn concentration in the tissues of green mussels and total Zinc, exchangeable (F1), acid-reducible (F2), and residual (F4) Zn in surface sediment. Green mussel Cu content and surface sediment Cu of exchangeable (F1), residual (F4), and total Cu were found to correlate. As a result, green mussels are being used as a biomonitoring agent for heavy metal contamination on the eastern side of the Straits of Johor in Malaysia.</p></div>","PeriodicalId":101255,"journal":{"name":"Total Environment Research Themes","volume":"7 ","pages":"Article 100064"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49730633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, there is a considerable drop in monsoon and winter precipitation, while both pre-monsoon and post-monsoon months witnessed an increasing precipitation trend, particularly over the past 50 years. A thorough review of the data for 50 years demonstrates that yearly temperature minimums and maximums have increased while the Guwahati city seasonal temperature minimums and maximums have also increased. The ARIMA findings indicated that annual average precipitation, maximum, minimum and average temperatures would quickly climb in coming years. The annual average values for precipitation, maximum, minimum and average temperatures would be 3988.5 mm, 35.75 °C, 23.33 °C and 28.40 °C, respectively by the year 2029.

Nano-clay has been observed for its unique characteristics and properties as an adsorbent in many adsorption processes for the last few years. The scope of the current review work is removing dye and heavy metals using Nano clay with special context to the effect of pH and temperature. Due to its high specific surface area (>800 m2/g), high cation exchange capacity (>120 cmol kg<sup>−1</sup>), low cost, and ability to be synthesised, Nano clay (NC) is known as an efficient adsorbent. To enhance the removal efficiency of NC, several studies reported the modifications of Nano-clay using different chemicals and polymers. Based on findings from the current analysis, it has been noted that Nano-Clay has promise as an adsorbent for almost all types of heavy metals and dyes. The review synthesis showed that the maximum removal varies from 31.5 to 2435.7 mg/g for Congo Red dyes and 9.02 to 100.09 mg/g (lead) for heavy metals by using Nano-clay.
