xenoestrogens are a type of xenohormone that imitates estrogen. they can be either synthetic or natural chemical compounds. synthetic xenoestrogens include some widely used industrial compounds, such as pcbs, bpa, and phthalates, which have estrogenic effects on a living organism even though they differ chemically from the estrogenic substances produced internally by the endocrine system of any organism. natural xenoestrogens include phytoestrogens which are plant-derived xenoestrogens. because the primary route of exposure to these compounds is by consumption of phytoestrogenic plants, they are sometimes called "dietary estrogens". mycoestrogens, estrogenic substances from fungi, are another type of xenoestrogen that are also considered mycotoxins.

handford was also known for his recordings of steam locomotives in the 1950s and 1960s, during the last days of steam railways in britain. these were issued on the transacord label between 1955 and 1961, at which point a deal was struck with argo, by then part of decca, for whom many new recordings were made under the "argo transacord" title. in 1980, argo was phased out by (british) decca's new owners, polygram and argo's owner, harley usill, started a new label, asv, on which new and reissued transacord lps were released in the early to late 1980s. the first cd was released in 1987 with others following in the 1990s. asv is now part of the sanctuary group (itself now owned by universal) and transacord recordings remained on catalogue on cd into the late 1990s, with some still readily available until comparatively recently (as at 2011). the majority of the cd tracks were later made available as digital downloads. however, the copyright in tranacord's recordings reverted from universal to transacord on 1 september 2011 at which point the digital downloads were made unavailable. transacord is currently looking at making both cds and digital downloads available again, possibly via the national railway museum, which organisation holds peter handford's original tape recordings and other materials from handford's private collections.
