Nova raziskava: Vse več mrtvih mladičev ptic zaradi sredstev proti bolham

Kemikalije, ki sov običajnih sredstvih proti bolham za pse in mačke onesnažujejo vode, vplivajo pa tudi na vse več smrti ptičjih mladičev.

Raziskava Univerze v Sussexu v Angliji je pokazala, da so insekticidi, ki so običajno v uporabi proti bolham za pse in mačke, prisotni v 98 % angleških rek, pogosto v količinah, ki presegajo varno mejo.

Nekaj tega lahko pripišemo plavanju psov, so dejali profesorji, ki so izvajali raziskavo, večinoma pa gre za ostanke teh sredstev, ki pridejo v vodo z odpadno vodo gospodinjstev – z umivanjem psov, pranjem posteljic in odej in umivanjem rok.

Nedavna raziskava, ki jo je financirala organizacija Songbird Survival (preživetje ptic pevk) pa je pokazala tudi, da niso onesnažene le vode, temveč tudi gnezda sinic, ki s pasjo in mačjo dlako poskrbijo za izolacijo svojih gnezd. Večja smrtnost mladičev je povezana z večjo ravnjo pesticidov.

Zato zdaj opozarjajo, da nikakor ne pomagamo pticam s pasjo dlako, če psa tretiramo z ampulami proti bolham ali drugim zajedavcem, pač pa vse krtačenje opravimo znotraj in poskrbimo za primerno odlaganje odpadle dlake v smeti. V nasprotnem primeru, če dlako prosto raznese po okolici, bo namreč skoraj zagotovo uporabljena za gnezda ptic.

Pomembno je tudi, da npr. ne spiramo prazne embalaže sredstev proti bolham, prav tako pa da psa nekaj dni po tretiranju ne kopamo.

It is used to ensure that the same poll does not re-appear if it has already been filled in. 365 days _hjMinimizedPolls Hotjar cookie. This cookie is set once a visitor minimizes a Feedback Poll widget. It is used to ensure that the widget stays minimizes when the visitor navigates through your site. 365 days _hjDoneTestersWidgets Hotjar cookie. This cookie is set once a visitor submits their information in the Recruit User Testers widget. It is used to ensure that the same form does not re-appear if it has already been filled in. 365 days _hjIncludedInSample Hotjar cookie. This session cookie is set to let Hotjar know whether that visitor is included in the sample which is used to generate funnels. 365 days _hjShownFeedbackMessage This cookie is set when a visitor minimizes or completes Incoming Feedback. This is done so that the Incoming Feedback will load as minimized immediately if they navigate to another page where it is set to show. 365 days _hjid Hotjar cookie. This cookie is set when the customer first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behavior in subsequent visits to the same site will be attributed to the same user ID. 365 days _hjRecordingLastActivity This should be found in sessionStorage (as opposed to cookies). This gets updated when a visitor recording starts and when data is sent through the WebSocket (the visitor performs an action that Hotjar records). Session hjTLDTest When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed. Session _hjUserAttributesHash User Attributes sent through the Hotjar Identify API are cached for the duration of the session in order to know when an attribute has changed and needs to be updated. Session _hjCachedUserAttributes This cookie stores User Attributes which are sent through the Hotjar Identify API, whenever the user is not in the sample. These attributes will only be saved if the user interacts with a Hotjar Feedback tool. Session _hjLocalStorageTest This cookie is used to check if the Hotjar Tracking Script can use local storage. If it can, a value of 1 is set in this cookie. The data stored in_hjLocalStorageTest has no expiration time, but it is deleted immediately after creating it so the expected storage time is under 100ms.
