Abstract
:Introduction
The Human Dimension to Environmental Quality
Definition of Key Terms
- Environment: Collective term used to describe all the living and non-living things that make up our surroundings. These include the biological, physical, cultural and social, economic and political environments [2]. For the purposes of this paper, environment will exclude the cultural, economic and political environments.
- Health: A state of complete physical, mental and social well-being of an individual and is not necessarily the absence of disease or infirmity [3].
- Environmental health: Defined as the control of those factors in the environment that may have deleterious effects on people’s physical, mental, or social well-being [4]. OR The effects of various environmental conditions on human health (author’s; derived from the definitions of environment and health).
- Conceptual: Related to or based on ideas [5].
- Guidelines: Rules or instructions that are given by an official organization telling you how to do something, especially something difficult [5].

Indoor Air Pollution: “Rule of One Thousand”
Environmental Tobacco Smoke
Health Impacts of Other Types of Air Pollution
Precautions to Guard against Indoor Air Pollution (Suggested by Authors)
- 1)
- The children’s home should not be located close to major sources of pollutants e.g. petrol stations, manufacturing plants, garages, and quarries.
- 2)
- Ensure that buildings housing the children’s home are well ventilated.
- 3)
- All fireplaces in the home must have properly designed chimneys to dispose of pollutants.
- 4)
- In homes that use jikos (charcoal stoves), home management should ensure that there is adequate air exchange whenever the stoves are in use.
- 5)
- The home environment should preferably be declared a no-smoking zone to protect the children from environmental tobacco smoke and to decrease any chances of children copying from adults the unhealthy habit of smoking.
Other Factors
Water Management & Usage
Rainwater Harvesting from Roofs
Treatment of Drinking Water
Diseases Transmitted through Water
Water Sampling
Waste Management
Health Risks of Inappropriate Excreta Disposal
Achieving Proper Disposal of Excreta in Children’s Homes - Suggestions by Authors
- 1)
- Ensure that the home has adequate user-friendly sanitary facilities. In case the toilets are flush type, it is preferable that the toilet bowls be the squatting-type instead of the sitting-type. This is because the former are more convenient to use by children and are also recommended for communal use.
- 2)
- In case the home uses pit latrines, they should be the modern improved ventilated pit latrine (VIP). These should be constructed under the supervision of the local public health officer or technician.
- 3)
- The home management should provide adequate anal cleansing materials e.g. old newspapers, toilet paper, water, etc. This will discourage the children from using their bare hands for anal cleansing and smearing excreta on the toilet walls.
- 4)
- Children should be taught to observe strict personal hygiene. Washing of hands after visiting the toilet should be made mandatory. Water in stand-pipes or leaking cans must be provided by home management.
Health Risks of Solid Waste
Measures to Achieve Better Solid Waste Management in Children’s Homes - Suggestions by Authors
- 1)
- Provide proper waste receptacles e.g. plastic bins with lid.
- 2)
- All waste generated should be stored covered in the bins to await collection in case a collection service is available.
- 3)
- In case a collection service is not available, the waste can be separated into combustible, non-combustible and biodegradable types. Combustible waste e.g. plastics, papers and polythenes should be disposed of by burning while biodegradable waste can be applied at the home garden as organic fertilizer. Noncombustibles such as metal cans, etc should be disposed of into a pit.
- 4)
- For (3) above to be achieved, source separation of waste is advisable i.e. there should be specific bins for each type of waste. In this case, three bins are required, each preferably marked according to waste type to be received.
- 5)
- Children should never be allowed to play with or near waste storage or disposal sites.
Malaria Prevention & Control
Measures for Prevention & Control - Suggestions by Authors
- 1)
- Provide all children resident in the home with insecticide-treated bed nets.
- 2)
- Carry out indoor residual spraying (IRS) in the home after every six months.
- 3)
- In areas with high mosquito density such as lowlands, provide window screening made of fine wire-mesh.
- 4)
- Use of insecticide-treated materials (ITMs) e.g. curtains, mbu cloth (i.e. piece of cloth treated with insecticide and hung on walls) is also encouraged in high-density mosquito areas.
- 5)
- Any receptacles such as tins, old tyres, old cups, etc that may collect rainwater and encourage mosquito breeding should be collected and disposed of appropriately.
- 6)
- Any stagnant water in or around the home should be drained by digging drainage channels or the pools filled with earth to prevent water from standing.
- 7)
- Bushes and long grass should not be allowed to proliferate in the home compound.
Prevention & Control of Vaccine-Preventable Diseases
Measles
Poliomyelitis
Precautions against Vaccine-Preventable Diseases - Suggestions by Authors
- (a)
- Before admitting any child into the home, his/her immunization status should be checked. The authority, relative or guardian from whose custody the child is taken should be able to provide this information.
- (b)
- If the child’s immunization status cannot be determined, then immediate advice should be sought from the local medical officer of health or the local health centre.
- (c)
- All children in the home must be immunized against all the vaccine-preventable diseases mentioned above.
Prevention of Physical Injuries
Accidents in the home
Physical violence/intentional injuries
Children’s play facilities
- a)
- Merry-go-round
- b)
- Slide
- c)
- Swing
- d)
- Toys
- e)
- See-saw
- f)
- Tunnel i.e. tyres placed vertically in a straight line with the lower ends slightly dug below the ground surface.
Nutrition
Food Safety
Biological Hazards in Food
Chemical Hazards in Food
Naturally-Occurring Chemicals
Precautions for Food Safety in the Homes - Suggestions by Authors
- 1)
- All kitchen workers involved in food preparation and handling must undergo medical examination after every six months. This will eliminate the risk of them acting as reservoirs/carriers of food-borne disease pathogens.
- 2)
- All foods must be properly and thoroughly cooked.
- 3)
- Kitchen workers must maintain proper personal hygiene i.e. washing hands after visiting toilet; short kempt hair; clean wear; short fingernails.
- 4)
- Food store should be clean, well aerated and free from any dampness that might encourage the growth of Aspergillus flavus (a mould) on grains.
- 5)
- Proper kitchen management should be observed i.e. cleanliness, separation of food preparation areas from waste storage area, cooking area and serving area and proper storage and disposal of kitchen waste.
- 6)
- To prevent the risk of consuming chemically-contaminated vegetables, the home management should verify the source of their supplies and prove that the vegetables are not grown on polluted soils e.g. sewage-irrigated fields and waste dumping sites.
- 7)
- Home management should ensure that beef and pork supplies to the home are duly inspected by the relevant authorities. Verification can be done simply by looking at inspection stamp or certificate.
Sexual Safety
Precautions for Sexual Safety - Suggestions by Authors
- 1)
- Improved security around the home to guard against sexual predators;
- 2)
- Rape-prevention education amongst girls in the home. This can be facilitated by a local anti-rape organization or a children’s rights lobby group within the region;
- 3)
- Sex and AIDS education. This can be conducted by teachers or health personnel. The focus should be on management of children’s (including adolescents) sexuality i.e. the appropriate conduct of both sexes towards each other.
- 4)
- Adolescent boys and girls should sleep in separate room;
- 5)
- Both boys and girls should not be presented with tempting opportunities e.g. allowing adolescent boys to visit girls’ rooms.
- 6)
- If sexual safety cannot be guaranteed at the home, options for making it a single-sex home should be considered.
Prevention of Chemical Poisoning/Chemical Safety
Precautions to Safeguard Chemical Safety- Suggestions by Authors
- 1)
- Do not keep chemicals in containers that the kids are familiar with and might confuse them e.g. soda bottles;
- 2)
- Keep all chemicals and medicines out of reach of children, probably in a lock-and-key store;
- 3)
- Dispose of chemical containers safely e.g. by burying deep in the ground or incineration;
- 4)
- Keep chemicals away from kitchen and food store to eliminate the danger of any accidental contamination;
- 5)
- Teach children the dangers of handling any chemicals.
