body mass index
the total amount of a chemical substance in the body. Some substances build up in the body because they are stored in fat or bone or because they leave the body very slowly.
wetland that has no significant inflows or outflows, supports acidophilic mosses, particularly Sphagnum and in which peat is accumulating. Similar to: fen, marsh, pocosin, swamp, and wetland.
breast cancer can begin in different areas of the breast – the ducts, the lobules, or in some cases, the tissue in between. The different types of breast cancer nclude non-invasive, invasive, recurrent, and metastatic breast cancers. Breast cancer may occur in men.
DCIS – Ductal Carcinoma In Situ
IDC – Invasive Ductal Carcinoma
IDC Type: Tubular Carcinoma of the Breast
IDC Type: Medullary Carcinoma of the Breast
IDC Type: Mucinous Carcinoma of the Breast
IDC Type: Papillary Carcinoma of the Breast
IDC Type: Cribriform Carcinoma of the Breast
ILC – Invasive Lobular Carcinoma
Inflammatory Breast Cancer
LCIS – Lobular Carcinoma In Situ

Paget's Disease of the Nipple
Phyllodes Tumors of the Breast
Recurrent and Metastatic Breast Cancer

investment on brownfield after clean-up. The economical backgroud of brownfiel reuse is the cost-benefit assessment: a beneficial new land use maybe able to cover the costs of the remediation/rehabilitation.
&show
brownfield or brownfield land is a moderately contaminated area previously were in industrial, mining, waste disposal or certain commercial uses. These sites have the potential to be reused once it is cleaned up.
benzene, or benzol, is an aromatic ring with the molecular formula C6H6. benzene is a colorless and flammable liquid with a strong smell and a relatively high melting point. Because it is a known carcinogen, its use as in gasoline is now limited, but it is an important industrialsolvent and precursor in the production of drugs and plastics. benzene is a natural constituent of mineral oil.
Alkylbenzenes are organic compounds that has an alkyl group bound to a benzene ring. Well known alkylbenzenes are methylbenzene, ethylbenzene and toluene, all of them are colorless flammable liquids obtained from petroleum or coal tar, used as a solvent for gums and lacquers and in high-octane fuels.
bulk density is a property of powders, granules and other "divided" solids, especially used in reference to mineral components (soil, gravel), chemical substances, (pharmaceutical) ingredients, foodstuff or any other masses of corpuscular or particulate matter. It is defined as the mass of many particles of the material divided by the total volume they occupy. The total volume includes particle volume, inter-particle void volume and internal pore volume.
Bulk density is not an intrinsic property of a material; it can change depending on how the material is handled. For example, a powder poured in to a cylinder will have a particular bulk density; if the cylinder is disturbed, the powder particles will move and usually settle closer together, resulting in a higher bulk density. For this reason, the bulk density of powders is usually reported both as "freely settled" (or "poured" density) and "tapped" density (where the tapped density refers to the bulk density of the powder after a specified compaction process, usually involving vibration of the container.)

a sample taken from a larger quantity (lot) for analysis or recording purposes.
a bushel is a British and U.S. customary unit of dry volume, equivalent in each of these systems to 4 pecks or 8 gallons. It is used for volumes of dry (not liquid) materials, most often in agriculture. The name derives from the 14th century buschel or busschel, a box. Its conversion to other units of volume:
bushels (US) | bushels (British) | 0.968 9 |
bushels (US) | cubic feet | 1.244 456 |
bushels (US) | cubic inches | 2,150.42 |
bushels (US) | cubic meters | 0.035 239 07 |
bushels (US) | cubic yards | 0.046 090 96 |
bushels (US) | dekaliters | 3.523 907 |
bushels (US) | dry pints | 64 |
bushels (US) | dry quarts | 32 |
bushels (US) | liters | 35.239 070 17 |
bushels (US) | pecks | 4 |
Body weight, used in toxicology for quantification of the intake by human, e.g. 3 mg/kg Bw, meaning 3 mg intake per kg.
