Risk assessment, an approach for organizing information about hazards to health, safety, and the environment, provides a framework for gauging the threat to child health from environmental pollutants. A qualitative risk assessment has 4 components: hazard identification, dose-response assessment, exposure assessment, and risk characterization. In a risk assessment, consideration can be given to a population group that potentially has increased susceptibility, whether arising from having a high level of exposure or from increased susceptibility to the agent of concern on a biological basis. Children have been proposed as being at increased risk from some environmental agents, and there has long been concern and debate that the current approach of determining acceptable exposure levels or intake for a person may not yield safe intake limits for infants and children, who may be placed at greater risk than adults because of exposure patterns and inherent susceptibility. The persistence of debate on this critical public health issue reflects, in part, the difficulty of developing sufficiently sensitive and validated animal bioassays for critical outcomes. Epidemiologic studies can play only a limited role, given the complexity of establishing cohorts and tracking exposures from conception forward to assess risks across the lifespan. Meeting society’s call for healthy environments for children poses an extraordinary challenge to researchers and to the policy makers who seek to develop evidence-based policies to protect children.

This paper explains how the results of the source water characterisation for the Western Corridor Recycled Water Project in South East Queensland was used to augment the qualitative water quality risk assessment process and design of the monitoring programs. Results were evaluated against health standards published in 2008 by Queensland Health and also against level of reporting. This determined the relative risk of exceeding the health standard for parameters detected in the source. The relative risk was used to inform the qualitative risk assessment as well as the frequency of monitoring in both the source and purified water. Categorising hazards using their ionic charge and hydrophobicity enabled the selection of indicators for both source and purified water compliance monitoring programs.

The problems of hazard identification in the structure of technological systems’ risk analysis are considered. Various methods of brainstorming used in the danger analysis are presented. It has been demonstrated that HAZOP investigation is the most structured brainstorming method for identification of system hazards. Roles, tasks and requirements for expert group’s leader and participants are considered. It has been demonstrated that experts’ competence needed for the hazard analysis does not meet the requirements to the competence for qualitative risk assessment. Decisions needed to achieve sufficient system safety must be taken after a quantitative risk assessment.

The aim of this paper was to answer some questions important for a qualitative risk assessment in poultry production related to Campylobacter. These steps are described: hazard identification, hazard characterization, exposure assessment and risk characterization. Hazard identification: Campylobacter is important cause of food borne diseases. Hazard characterization: human campylobacteriosis is assumed to be dose-independent based on some studies on healthy human volunteers. Exposure assessment: Campylobacter colonization and spread of Campylobacter on poultry carcasses were described. Our results indicate high prevalence of Campylobacter spp. in intestines of poultry, the clinical symptoms of campylobacteriosis usually depends of the age and additional immunosupresive factors, such as Salmonella. According to our experimental results artificial infection of chickens with 6.77 log cfu C. jejuni per chicken on day 21 of life leads to 5.26 log cfu/g feces after 5 days, with slight decrease in next 20 days and return to starting level in next 20 days. According to our experimental results, slaughtering of Campylobacter positive flock appears where 100% birds (with 3.02 log cfu/g feces) is contaminated lids to 50% contaminated carcasses. High prevalence of Campylobacter spp. was also found on poultry carcasses in our slaughterhuoses. Risk characterization: on the basis of the performed examinations it can be concluded that even there is high exposure of human population to Campylobacter from poultry meat; the incidence of human campilobacteriosis is low, mainly because there is a lack of evidence and confirmation of human campylobacteriosis.

The need to focus on banks funding structure and stress testing in an explicit way arose as a consequence of the crisis of past decades. Liquidity risks usually occur as a consequence of other kinds of risks, hence analysing scenarios in a prospective manner is essential for the assessment if the bank can fulfill its obligations as they come due and if its funding costs are appropriate. The structural liquidity risk and the degree of the liquidity mismatch can be measured based on the liquidity gap analysis, where expected cash-in- and outflows, divided in different time-buckets are depicted. The liquidity gap report (LGR) shows if a liquidity shortcoming appears in the future and how high is the amount a bank would have to pay, if any hedging were not possible. This paper shows how to build a comprehensive LGR which is the base for both, liquidity and wealth risk evaluation. To improve the accuracy of the forecast, the counterbalancing capacity will be incorporated into the LGR. This tool is a methodological basis for quantitative and qualitative risk assessment and stress testing.

BACKGROUND: The COVID-19 global pandemic brought several challenges to occupational safety and health practice. One of these is the need to (re)assess the occupational risks, particularly, biological risks. OBJECTIVE: The purpose of this work is to promote guidance to occupational safety and health practitioners when conducting a biological risk assessment in this context. METHODS: The main steps of the biological risk assessment are explained with some inputs regarding the novelty posed by SARS-CoV-2 and an example of a qualitative risk assessment method is presented. Also, its application to two different activities was exemplified. RESULTS: In both cases, the assessment considered that vulnerable workers were working from home or in medical leave. The results showed low or medium risk level for the assessed tasks. For medium risk level, additional controls are advised, such maintain social distancing, sanitize instruments/equipment before use, use proper and well-maintained PPE (when applicable), and promote awareness sessions to spread good practices at work. Employers must be aware of their obligations regarding biological risk assessment and OSH practitioners must be prepared to screen and link the abundance of scientific evidence generated following the outbreak, with the technical practice. CONCLUSIONS: This paper could be an important contribution to OSH practice since it highlights the need to (re)assess occupational risks, especially biological risk, to ensure a safe return to work, providing technical guidance.

The International Maritime Organization (IMO) published the Guidelines on Maritime Cyber Risk Management in 2017 to strengthen cybersecurity in consideration of digitalized ships. As part of these guidelines, the IMO recommends that each flag state should integrate and manage matters regarding cyber risk in the ship safety management system (SMS) according to the International Safety Management Code (ISM Code) before the first annual verification that takes place on or after 1 January 2021. The purpose of this paper is to identify cybersecurity risk components in the maritime sector that should be managed by the SMS in 2021 and to derive priorities for vulnerability improvement plans through itemized risk assessment. To this end, qualitative risk assessment (RA) was carried out for administrative, technical, and physical security risk components based on industry and international standards, which were additionally presented in the IMO guidelines. Based on the risk matrix from the RA analysis results, a survey on improving cybersecurity vulnerabilities in the maritime sector was conducted, and the analytic hierarchy process was used to analyze the results and derive improvement plan priority measures.
