Insight into the mechanisms of combined toxicity of cadmium and flotation agents in luminescent bacteria: Role of micro/nano particles. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 940:173588. [PMID: 38823693 DOI: 10.1016/j.scitotenv.2024.173588] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 05/22/2024] [Accepted: 05/26/2024] [Indexed: 06/03/2024]
Abstract
Currently, risk assessment and pollution management in mines primarily focus on toxic metals, with the flotation agents being overlooked. However, the combined effects of metals and flotation agents in mines remain largely unknown. Therefore, this study aimed to evaluate the combined effects of Cd and two organic flotation agents (ethyl xanthate (EX) and diethyldithiocarbamate (DDTC)), and the associated mechanisms. The results showed that Cd + EX and Cd + DDTC exhibited synergistic toxicity. The EC50 values for luminescent bacteria were 1.6 mg/L and 1.0 mg/L at toxicity unit ratios of 0.3 and 1, respectively. The synergistic effects were closely related with the formation of Cd(EX)2 and Cd(DDTC)2 micro/nano particles, with nano-particles exhibiting higher toxicity. We observed severe cell membrane damage and cell shrinkage of the luminescent bacteria, which were probably caused by secondary harm to cells through the released CS2 during their decomposition inside cells. In addition, these particles induced toxicity by altering cellular levels of biochemical markers and the transcriptional levels of transport proteins and lipoproteins, leading to cell membrane impairment and DNA damage. This study has demonstrated that particulates formed by Cd and flotation agents contribute to the majority of the toxicity of the binary mixture. This study helps to better understand the complex ecological risk of inorganic metals and organic flotation agents in realistic mining environments.

The concentration of potentially toxic elements (PTEs) in apple fruit: a global systematic review, meta-analysis, and health risk assessment. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2022; 29:54013-54024. [PMID: 35648350 DOI: 10.1007/s11356-022-21158-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 05/24/2022] [Indexed: 06/15/2023]
Abstract
The presence of potentially toxic elements (PTEs) in crops can directly/indirectly affect consumers' health. The contamination of apple as one of the most consumed fruits with PTEs such as lead (Pb), cadmium (Cd), chromium (Cr), arsenic (As), and nickel (Ni) leads to carcinogenic risk (CR) and non-carcinogenic risk (n-CR). In this regard, a systematic review, meta-analysis, and health risk assessment regarding the concentration of the PTEs in apples was conducted using international databases such as Scopus and PubMed. According to the results, the rank order of PTEs in apple fruits was Pb (427.45 µg/kg-wet weight) > Ni (228.74 µg/kg-wet weight) > Cr (212.43 µg/kg-wet weight) > As (123.93 µg/kg-wet weight) > Cd (15.28 µg/kg-wet weight). n-CR was higher than 1 for the USA, Serbia for adults, and Poland for children. CR for adults in Serbia, Spain, Greece, China, Bangladesh, and Pakistan and children in Serbia, Spain, Greece, China, and Bangladesh were not acceptable (CR > 1.00E - 06 value). In this regard, the pooled PTEs of apples can cause CR and n-CR issues. Therefore, constant monitoring and reduction of pesticide application are strongly recommended for controlling PTEs in apple fruits.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17186783. [PMID: 32957581 PMCID: PMC7559543 DOI: 10.3390/ijerph17186783] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/08/2020] [Revised: 09/08/2020] [Accepted: 09/12/2020] [Indexed: 01/24/2023]
Abstract
Although extensive research exists on toxic environments in the Tri-State Mining District (TSMD), there has been a lack of research on how harmful effects in TSMD could affect residents living in those areas. However, quite recently, such research regarding relationships between the health conditions of residents and toxic elements in the TSMD began to grow. The increase of empirical studies means greater complexity of the findings that require a more intricate understanding. To meet the goals of this study, an extensive, systematic review of the literature using PRISMA was conducted. This method resulted in 19 articles that define the harmful effects of the TSMD on the ecology and the physical health of residents. This research found that toxic metals not only negatively impact natural processes in the TSMD environments (fish species reduction, kidney and liver problems, and toxic diet) but also continuously affect the health of residents (high blood Pb and mortality).This study makes a vital contribution building upon the existing outcomes of the correlations between toxic elements in the TSMD areas and the health of residents. Furthermore, conclusions of this study provide updated information to policymakers and health-related professionals by providing adequate and innovative remediations and health-related services in the TSMD.
