“…According to the regional environmental risk system (Liu et al, 2013), any single risk route potentially leads to a water pollution accident that is deemed to have occurred when an enviro nmental pollution hazard is triggered (i.e. sudden release of toxic chemicals or heavy metals), and when its residual impact on a vulnerable risk receptor (e.g.…”

“…Herein, focusing on stationary stressors, we use a complete index system to evaluate the hazard degree within a mapping unit based on formulae derived by Liu et al, (2013). Considering the inherent hazard of stressors and the operability of assessment, simplified multiple criteria are then derived for the stressors' hazard analysis from the derived formulae, which have been adopted into a national guidebook (China MEP, 2014).…”

“…Receptors that might potentially be exposed to a water pollution hazard comprise drinking water intakes, irrigation water intakes, water bodies, residential land, agricultural land, woodland, and nature reserves. Receptor vulnerability describes the levels susceptible to loss and damage, following Liu et al (2013). The size and sensitivity of a receptor is used to rank its vulnerability in three grades, 6, 4, and 2, in accordance with national criteria or expert judgment (see Table 3).…”

“…The risk route score is calculated by multiplying together the hazard ranking ( H), vulnerability ranking (V), exposure filter (Ex), and effect filter (Ef) (see Wieger et al, 1998;Liu et al, 2013 integrating all risk routes which end within the same sub-watershed. Interval breaks of 500, 1000, and 1500 are used to rank the risk levels of the sub-watersheds as low, medium, high, and very high.…”

“…The marine oil spill risk indexes should have the characteristics that discriminate the degree of oil spill risk for each unit, Furthermore, the indexes should be complete, operative, causative, scientific and independent (Liu et al, , 2013. In this paper, the index system is constructed based on the study of marine oil spill risk system (Table 1).…”

BackgroundDeveloping nations have to overcome a number of obstacles to fulfill the Sustainable Development Goals. The Democratic Republic of Congo is one of the five poorest nations in the world and faces several challenges in combating problems related to poverty, health, and sanitation while linking the environment to anthropogenic activities.MethodsThis study analyzes anthropogenic activities and their impact on the environment while providing access to the public health of the Congolese population based on the objectives of sustainable development. Thirty‐five articles were selected for further analysis as well as relative data.ResultsIn 2022, 21 million cases of malaria were recorded by the national malaria control program, with 13,000 cases of death. The Democratic Republic of Congo has the highest typhoid incidence, with 315 cases per 100,000 people. A number of 31,342 cases of cholera were reported in 2023, according to multiple reports, with 230 deaths, mainly affecting children. In the same year, a triple epidemic of typhoid, shigellosis, and cholera was identified, with 2389 cases and 52 deaths. These observations cause a health emergency, which can be alleviated and resolved by the establishment of an adequate sanitation system. Waste can be recycled and returned to usable raw materials.ConclusionFinally, it will be necessary to establish a water safety management plan to combat all diseases linked to the consumption of nonpotable water and improve national coverage on the treatment of recent cases to reduce and at best avoid observed cases of death.
