Phthalic acid
Phthalic acid is an aromatic dicarboxylic acid, with formula C6H4(COOH)2. Phthalic acid is used mainly in the form of the anhydride to produce other chemicals such as dyes, perfumes, saccharin, phthalates and many other useful products. Phthalic acid, when found in tissues or biofluids arises from exposure to these phthalate products. Phthalate is an environmental chemical of heightened public concern because reports of its potential risk to male reproductive health (PMID 16804814), being significantly associated with reduced sperm concentration to pesticide concentration in mens urine (PMID 16804812). Within the reproductive tract, the male is exquisitely vulnerable to the effects of anti-androgens during development due the reliance on the synthesis and action of androgens for the masculinization of the male reproductive tract. The ability of phthalates to suppress androgen synthesis during development and to induce testicular dysgenesis together with cryptorchidism and hypospadias has raised considerable concern.

Benzoquinoneacetic acid
Benzoquinoneacetic acid (BQA) is an oxidized form of homogentisic acid. The oxidation of homogentisic acid to BQA is catalyzed by the enzyme polyphenol oxidase. BQA is secreted in high quantities in the urine of patients suffering from cyanosis caused by vitamin C deficiency (Ella H. Fishberg, J. Biol. Chem., Jan 1948; 172: 155 - 163). Cyanosis is the bluish colouration of the skin due to the presence of deoxygenated hemoglobin in blood vessels near the skin surface. When present in sufficiently high levels, BQA can function as an osteotoxin and a renal toxin. An osteotoxin is a substance that causes damage to bones and/or joints. A renal toxin causes damage to the kidneys. Chronically high levels of BQA are associated with alkaptonuria (OMIM: 203500), an inborn error of metabolism. Alkaptonuria is a rare inherited genetic disorder in which the body cannot process the amino acids phenylalanine and tyrosine. It is caused by a mutation in the enzyme homogentisate 1,2-dioxygenase (EC 1.13.11.5), which leads to an accumulation of both homogentisic acid and BQA in the blood and tissues. When excreted in the urine, these compounds give it an unusually dark color. The accumulating BQA causes damage to cartilage (ochronosis, leading to osteoarthritis) and heart valves as well as precipitating as kidney stones and stones in other organs. More specifically, BQA can form polymers that resemble the dark skin pigment melanin. These are deposited in collagen, especially in tissues such as cartilage. This process is called ochronosis (as the tissue looks ochre); ochronotic tissue is stiffened and unusually brittle, impairing its normal function and causing damage. Benzoquinoneacetic acid is an oxidized phase of the oxidation-reduction system homogentisic-benzoquinoneacetic acid. This compound is secreted in large quantities in the urine of patients suffering from cyanosis. Cyanosis is the bluish coloration of the skin due to the presence of deoxygenated hemoglobin in blood vessels near the skin surface. (Ella H. Fishberg, J. Biol. Chem., Jan 1948; 172: 155 - 163; Wikipedia) [HMDB]
