“…All of these viruses produced substantial respiratory difficulties, with most people dying (Geller et al., 2012; Morens et al., 2004), while some people could live due to strong immunity. The human coronavirus can kill up to 30% of those afflicted (Hao et al., 2021), based on the risk factor (Zhou et al., 2020). The current COVID‐19, initially identified in December 2019 in Wuhan, China, started as a series of severe pneumonia episodes (Sun et al., 2020).…”

“…Later, the disease caused by SARS‐CoV‐2 was named COVID‐19 by World Health Organization (WHO) (Zu et al., 2020). In January 2020, WHO declared COVID‐19 a public health emergency of international concern, and later on, in March 2020, WHO recognized it as a pandemic (Hao et al., 2021; Wang et al., 2020; WHO Emergency Committee, 2020). Regular hand‐washing, the use of alcohol‐based hand sanitizers, and hand rubs as quick hand hygienic solutions are among the hygienic methods recommended by WHO to avoid the spread of COVID‐19.…”

The coronavirus outbreak threatens global well-being, costing thousands of lives and an unstable economy. Traditional hand-washing (HaWa) with clean water and hand-washing sanitizers (HaWaSas) are among WHO recommended practices against the outbreaks. HaWaSa and HaWa lacked proper quality monitoring evaluation that may pose health risks. The current study investigates the potential of traditional hygienic practices adopted to mitigate the 2019-2020 Pandemic. It involved assessing the effectiveness of 15 HaWaSa collected from the Dodoma market. Thirty volunteered participants were subjected to different hygienic practices involving HaWa and HaWaSa. The obtained hand-swabbed samples were subjected to the streak plate technique for inoculation, followed by counting colonies. The results revealed that, among the collected HaWaSa brands, only 33.3% were certified by the Tanzania Bureau of Standards (TBS). In the setting under no hand-wash, each client had a different number of colony counts. HaWa did not eliminate all colonies since water acted as a secondary source while only one sanitizer proved effective. The p-values obtained in either setting were greater than 0.05, indicating that each variable was independent. Despite global awareness and fighting against the Coronavirus Disease 2019 (Covid-19) outbreak, quality monitoring of all diagnostic tools, preventive HaWaSa, and related drugs should be prioritized for human safeguard.

“…Although the concentration of SCCP in the ECS was lower than those in the Bohai Sea and Yellow Sea, high levels were still observed in the YRE and near-shore coastal waters of the ECS.

“…As an excellent marine ranching zone for marine fish species, 61 its pollution has received considerable attention in recent years. Hao et al 61 investigated the typical POCs in surficial sediments in the Eastern China Marginal Seas. The results showed that the concentrations of SCCP in sediments of the ECS (mean: 22.50 ng g −1 ) were much higher than those of organochlorine pesticides (mean: 2.71 ng g −1 ) and perfluoroalkyl substances (mean: 0.72 ng g −1 ).…”

Increasing global and domestic food trade and required logistics create uncertainties in food safety inspection due to uncertainties in food origins and extensive trade activities. Modern blockchain techniques have been developed to inform consumers of food origins but do not provide food safety information in many cases. A novel food safety tracking and modeling framework for quantifying toxic chemical levels in the food and the food origins was developed. By integrating chemicals’ multimedia environment exchange, food web, and source tracking systems, the framework was implemented to identify short-chain chlorinated paraffin (SCCP) contamination of fresh hairtail fish sold by a Walmart supermarket in Xi’an, northwestern China, and sourced in Eastern China Sea coastal waters. The framework was shown to successfully predict SCCP level with a mean of 17.8 ng g–1 in Walmart-sold hairtails, which was comparable to lab-analyzed 21.9 ng g–1 in Walmart-sold hairtails. The framework provides an alternative and cost-effective approach for safe food inspection compared to traditional food safety inspection techniques. These encouraging results suggest that the approach and rationale reported here could add additional information to the food origin tracking system to enhance transparency and consumers’ confidence in the traded food they consumed.

“…Persistent organic pollutants (POPs) have characteristics that include persistence, toxicity, and biological accumulation and have a great impact on air quality (Hao et al, 2021;Sari et al, 2021). As a sub-group of persistent organic pollutants, PCDD/Fs (polydibenzo-p-dioxins and polydibenzofurans) are high similar in terms of structure and properties (Schecter et al, 2006).…”

Wet deposition is an important mechanism for removing air pollutants from the atmosphere. The total PCDD/Fs-WHO2005-TEQ wet deposition from 2018-2020 was investigated for Beijing and Tianjin City in this study. In addition, the gas-particle partitioning of wet deposition, the total PCDD/Fs-WHO2005-TEQ concentrations in the rain, the PM2.5-bound total PCDD/Fs-WHO2005-TEQ content, and the PM2.5 concentration were also studied for Beijing and Tianjin City, respectively. Between 2018 to 2020, as a whole, the average seasonal variations in PCDD/F wet deposition fluxes in spring, summer, fall, and winter were 50.50, 41.47, 23.03 and 16.76 pg WHO2005-TEQ m -2 month -1 , respectively, while in Tianjin, they were 35.30, 42.40, 13.37, and 14.77 pg WHO2005-TEQ m -2 month -1 , respectively. Because the two cities have more rainfall in spring and summer than they do in fall and winter, rainfall has a significant influence on the wet deposition flux. In regard to PCDD/Fs-WHO2005-TEQ in the rain, in Beijing, the average total PCDD/Fs-WHO2005-TEQ concentration in the rain in spring, summer, fall, and winter were 1.70, 0.39, 1.42, and 1.52 pg WHO2005-TEQ L -1 , respectively, while those in Tianjin, were 1.73, 0.42, 1.35, and 1.88 pg WHO2005-TEQ L -1 , respectively. The above results show that the total PCDD/Fs-WHO2005-TEQ concentrations in the rain are significantly lower in summer, which is mainly due to the fact that in summer, the total PCDD/Fs-WHO2005-TEQ concentrations in the air are lower, and the proportion of the gas phase is increased. When the total PCDD/Fs-WHO2005-TEQ concentrations in the air are washed away by a heavy rainfall, the PCDD/F concentrations are diluted.
