Volatile Organic Compound
Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. They are common and exist in a variety of settings and products, not limited to Indoor mold, house mold, Upholstery, upholstered furniture, Handicraft, arts and crafts supplies, Dry cleaning, dry cleaned clothing, and Cleaning agent, cleaning supplies. VOCs are responsible for the odor of scents and perfumes as well as pollutants. They play an important role in communication between animals and plants, such as attractants for pollinators, protection from predation, and even inter-plant interactions. Some VOCs are dangerous to human health or cause harm to the natural environment, environment, often despite the odor being perceived as pleasant, such as "new car smell". Human impact on the environment, Anthropogenic VOCs are regulated by law, especially indoors, where concentrations are the highest. Most VOCs are not acutely toxic, but may have long-term chronic health effect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Construction Waste
Construction waste or debris is any kind of debris from the construction process. Different government agencies have clear definitions. For example, the United States Environmental Protection Agency EPA defines construction and demolition materials as “debris generated during the construction, renovation and demolition of buildings, roads, and bridges.” Additionally, the EPA has categorized Construction and Demolition (C&D) waste into three categories: non-dangerous, hazardous, and semi-hazardous. Of total construction and demolition (C&D) waste in the United States, 90% comes from the demolition of structures, while waste generated during construction accounts for less than 10%. Construction waste frequently includes materials that are hazardous if disposed of in landfills. Such items include fluorescent lights, batteries, and other electrical equipment. Waste from a construction project can contain "microplastics, PFAS, titanium dioxide, dyes and various chemicals and ...

Pollutant
A pollutant or novel entity is a substance or energy introduced into the environment that has undesired effect, or adversely affects the usefulness of a resource. These can be both naturally forming (i.e. minerals or extracted compounds like oil) or anthropogenic in origin (i.e. manufactured materials or byproducts). Pollutants result in environmental pollution or become of public health concern when they reach a concentration high enough to have significant negative impacts. A pollutant may cause long- or short-term damage by changing the growth rate of plant or animal species, or by interfering with resources used by humans, human health or wellbeing, or property values. Some pollutants are biodegradable and therefore will not persist in the environment in a long term. However, the degradation products of some pollutants are themselves pollutants such as DDE and DDD produced from the degradation of DDT. Pollution has widespread negative impact on the environment.

Particulates
Particulate matter (PM) or particulates are microscopic particles of solid or liquid matter suspension (chemistry), suspended in the atmosphere of Earth, air. An ''aerosol'' is a mixture of particulates and air, as opposed to the particulate matter alone, though it is sometimes defined as a subset of aerosol terminology. Sources of particulate matter can be natural or anthropogenic hazard, anthropogenic. Particulates have impacts on climate and precipitation that adversely affect human health. Types of atmosphere, atmospheric particles include suspended particulate matter; thoracic and respirable particles; inhalable coarse particles, designated PM, which are granularity, coarse particles with a particle size, diameter of 10 micrometre, micrometers (μm) or less; fine particles, designated PM, with a diameter of 2.5 μm or less; ultrafine particles, with a diameter of 100 nm or less; and soot. Airborne particulate matter is a List of IARC Group 1 carcinogens, Group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Renovation
Renovation (also called remodeling) is the process of improving broken, damaged, or outdated structures. Renovations are typically done on either commercial or residential buildings. Additionally, renovation can refer to making something new, or bringing something back to life and can apply in social contexts. For example, a community can be renovated if it is strengthened and revived. It can also be restoring something to a former better state (as by cleaning, repairing, or rebuilding). Renovation is very common in some places. For example, there are more than twenty thousand home improvement projects every year in Hong Kong, affecting more than a million residents (population of HK is around 7.5 million in 2023). Phases and process of renovations The building renovation process can usually, depending on the extents of the renovation, be broken down into several phases. The phases are as follow. *Project initiation - The beginning of the project that includes the hiring of c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Fugitive Dust
Fugitive dust is an environmental air quality term for very small particles suspended in the air, primarily mineral dust that is sourced from the soil of Earth's pedosphere. A significant volume of fugitive dust that is visible from a distance is known as a ''dust cloud'', and a large dust cloud driven by a gust front is known as a dust storm. Fugitive dust particles are mainly minerals common to soil, including silicon oxides, aluminum oxides, calcium carbonates and iron oxides. About half of fugitive dust particles are larger than 10 micrometres in diameter and settle more quickly than the smaller particles. It does not include particulate matter from other common artificial sources such as vehicle exhaust, burn piles or smokestacks. The term is used to denote that the dust "escapes" into the atmosphere rather than being exhausted in a "confined flow stream" from a "ducted emitter" (an exhaust pipe or chimney). The U.S. Environmental Protection Agency estimated that fugit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Roadwork
Roadworks, also called road construction or road work, occur when part of the road, or in rare cases, the entire road, has to be occupied for work relating to the road, most often in the case of road surface repairs. In the United States road work could also mean any work conducted in close proximity of travel way ( thoroughfare) such as utility work or work on power lines (i.e. telephone poles). The general term of road work is known as work zone. Roadworks can, however, also happen when a major accident occurs and road debris from the crash needs to be cleared. Roadworks are often signposted, although it is possible that the signage comes too late or too sudden or is missing. Typical road work traffic controls are temporary signs, traffic cones, barrier boards and t-top bollards as well as other forms of warning devices. There are standards of temporary traffic control established in each country for various type of road work. Usually, roadworks takes place at night, b ...

Concrete Batching Plant
Concrete is a composite material composed of construction aggregate, aggregate bound together with a fluid cement that curing (chemistry), cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic process, exothermic, which means that room temperature, ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
